Intrinsic motivation, extrinsic motivation, and achievement motivation are different types of motivation that are discussed in relation with performance, work-satisfaction, and flow experiences (Rheinberg, 2008). However, these terms have not been used consistently throughout the literature (see Rheinberg, 2008 for a review). Though intrinsic motivation and achievement motivation overlap in their outcomes, they are not conceptually the same. This symposium combines research that (1) examines whether these concepts are distinct from each other and whether they allow for differential predictions, (2) conditions under which intrinsic motivation and extrinsic motivation work well together in achievement-related activities, and (3) the impact of manager and coworker support on intrinsic work motivation and goal achievement.Is Intrinsic Motivation Distinct from Achievement Motivation?Presenter: Marylene Gagne; Concordia U.Presenter: Kaspar Philipp Schattke; Concordia U.Presenter: Edwin A.
